For media center volunteers or inexperienced technicians, a workshop training guide provides reference and assistance in everyday problems and situations that arise in an instructional material center (IMC). Two five-hour days of instruction and participation, using the guide, are suggested for workshops. Step-by-step processing of book materials, using printed card sets and kits, is demonstrated. Samples of cards and media inventory lists are provided. Basic equipment and supplies of a media center are listed and described. (SK)
